Ernst Stromer was inspired by the
Rhamphorhynchus wing membranes that were published in the 1880's.
With the wing membrane known in its general proportions, it did
not take long to develop a glider that would test the basic gliding
capability of this species. Stromer produced a flying glider in 1913
which demonstrated that Rhamphorhynchus could glide easily with the
known wing form.

Ernst Freiherr Stromer von Reichenbach (1870 – 1952) was a renowned German
Palaeontologist credited with the discovery of Spinosaurus and Aegyptosaurus.
The title Freiherr is essentially a civil rank equating to Baron in English.
